Application July 18, 1933, Serial No. 680,903

This invention relates to new and useful improvements in means forlocating the manual control of the operating switch on, especially,upright electric fixtures, such as are used in what are commonly knownas floor and table lamps;

and among the varied objects of my improvements the most essentiallyare, to provide a manual control for the operating switch in the mosteasily accessible part of said fixture, and to afiord a manual controlof the operating switch, which by its design, construction and location,will serve as an added decorative adornment of this kind of lamps.

In the drawings are shown two embodiments, which will illustrate theapplication of this invention on the two main types of decorative fiooror table lamps, which types differ in principle thereby that in case ofthe first type, the light emitting bulb is arranged, so as to extendupwardly from any suitable parts of the lamp fixture, and below thoseother fixture parts, which carry the lamp shade, whereas in the secondtype of the decorative floor lamps or table lamps, the light emittingbulb is downwardly directed and suspended directly from the lampshadecarrier.

With the above and other objects in view, this invention consists of thenovel features of construction, combination and arrangement of parts,hereinafter fully described, claimed and illustrated in the accompanyingdrawings forming part of this specification, and in which similarcharacters of reference indicate corresponding parts in all views, andin which:

Figure 1 is a partly sectioned elevation of a lamp arrangement of thefirst said type.

Figure 2 is a partly sectioned elevation of a lamp arrangement of thesecond type.

Figures 3 and 4 are top views on the different parts of the constructionat the switch-carrying upper end of the lamp shown in Figure 1.

Figures 5, 6 and 7 are a top view of, and two crosswise verticalsections, respectively, through the switch-carrying, and shade-holdingparts in a lamp of the second type, according to the Figure 2.

Referring more particularly to the drawings in the shown construction ofthe first embodiment (Figuresl, 3 and 4), a bottom-nipple 11 is providedat its lower part, with an outer male thread, to screw it on to anysuitable lamp base, standard or pedestal; the upper part of the saidnipple having an inner female thread, into which is screwed any standardkind of electric bulb socket 12. The middle zone 01 the said nipple hastwo diametrically arranged holes, from the outer ends of which the twotubular arms 14, 15 commence, said tubular arms are bent upwardly so asto form together a loop, and at the uppermost wider part of this loopthe two arms 14., 15 hold between them the housing 16 for the electricswitch 1'7.

This switch will be preferably of the two pole rotating type, and theupwardly elongated central part 18 of the switch body is provided with ascrew-thread, on which may be screwed :1. mt hexagonal lock-nut, 19. Theshade-carrier consists of a ring 20, with radially extending arms 21,and is placed on the lid of the switch-housl5 ing 16, and fixed theretoby the lock-nut 19. The rotatable switch-shaft 22 passes loosely throughthe switch-body elongation 18; and the threaded upper end 22 of theswitch-shaft carries the switch knob or handle 23.

The wiring in this embodiment of the floor lamp or'table lamp is asfollows: The two-eonductor cable 24 enters from below into the nipple11; the one insulated conductor 25, goes directly to the one terminal ofthe bulb socket 12, 25 while the other insulated conductor 26, turnsfrom the nipple 11 into the one tubular arm 14 and at the upper end ofthis arm the conductor 26 enters into the switch-housing 16 contactingwith the one switch-terminal. From the other 3 switch-terminal startsthe conductor 2'1, which goes through the other tubular arm 15 back intothe nipple 11 and further to the cable 24. Where safety requirementsdemand double pole switches the tubular arms 14 and 15 may be 5 designedto hold :both conductors 25 and 26 as a double conductor in each arm.

The second embodiment of the invention. as shown in the Figures 2, 5, 6and 7, contains likewise a lower threaded nipple 28, to be screwed on toany suitable lamp base, standard or pedestal. in which nipple the lowerends of the tubular arms 29, 30 are fixed; said arms are bent to form aframe of the so called lyre-shape. The upper ends of this frame or yokehold a slightly offset cylindrical box 31, 32, with an inner insulatinglining, and the lower part 31 of this box serves, by means of a suitableinner metallic outfit, as a bulb-socket, whereas the upper part 32 ofthis box serves as a switch- 5 housing. The upper lid of theswitch-housing is provided with a perforated central plug 33, having ascrewthreaded upper end, adapted to receive the flat hexagonal lock-nut34. The shade-carrier, consisting of a ring 35 with radino allyextending arms 36, is placed on the "lid of the switch-housing 32, andsecured firmly at this position by the lock-nut 34. In this embodimentlikewise a two-pole switch of the rotating type has been provided, asthe shaft 37 of the rotor-part of this switch passes loosely through thelid 01' the switch-housing and through the plug 33; and the upperscrewthreaded end of this shaft carries the switch grip or handle 38.

The stationary body-part or the switch is a block 39 of insulatingmaterial, inserted into the switch-housing 32 and provided with a numberof suitable recesses to accommodate the metallic current conductingparts of the switch. In one 01 these recesses is fixed the oneswitch-terminal 40, which is in metallic connection with the oneterminal of the bulb-socket, namely with the threaded shell 41 of thissocket. Diametrically opposite to the first recess of the switchbody isanother vertical recess 42, the upper end 01' which 15 broadened by abent channel 43,

centre of the top part of the switch-body 39 is a cavity, containing therotor part 44 01' the switch and the two cooperating resilient contacttongues the one of these contacting tongues 55 terminating in theaforesaid channel 43, the other of the contact tongues 55 beingconnected with a conductor 56, which leads through another ve icalrecess 57 (see Fig.

other terminal 58 of the bulb socket.

The rest of the electric wiring of this type of lamps consists simply inthe two-core cable 59, which branches at the lower nipple 28; the onebranch 60 going through the one tubular arm 29 to the oneswitch-terminal 40, and the other cable-branch 61 going through theother tubular arm 30 and through the recess 42 and channel 48 to thecorresponding contact-tongue or spring 55.

The operation, and the working of the switch is like in ordinarylighting fixtures, so that it will not be necessary to trace herein indetail the flow of the current.

It is important appended claim, spirit of the invention, and I do nottherefore wish to limit myself to the construction and arrangement shownand described herein.

Having thus described my invention, what I claim as new and desire tosecure by letters Patent 01 the United States, is:

In-alighting fixture adapter of the character described, a standard basenipple, a lamp socket attached to the upwardly extending end of saidnipple, said nipple carrying two outward and upwardly extending tubularsupports terminating in a switch housing, an insulated electric thetopmost end of said shaft, whereby said switch may be operated andwhereby the lighting fixture adapter may be suitable for any type ofshade.
